Oxygen Sensor Application Guide:

P93H 3.8L GM P/N: 25162693 AC P/N: AFS20 POSN 1
P93H 3.8-1 GM P/N: 25162693 AC P/N: AFS20 POSN 1

Something is wrong with the chart, because in 93, the */C engine did not use a heated sensor, while the N/A engine did. The part numbers should be different.

Mine is a single wire....unheated. JSeabert'* is a heated. He'* a 93 NA. Go figure. This is one of the things that caused so much confusion early on. My magic book actually gave me the right number for mine (25162693) but that'* the only one listed for 92/93, and Josh'* is different. Jr, take a look at the book I sent you and you'll see what I mean. It also shows one part number for 94/95, another for 96/97, and another for 98/99. I don't trust any of this any more......but it'* the only apparent bum info in my book.

You guys that didnt buy a o2 socket must be a sight more nimble than I.

I had to go buy a socket but I'm just going to return it when I am done with it.

I just changed mine today with a 8" Adjustable wrench. It was fine and easy to change - I was surprised actually.

The T-stat was more messy but did it. It is running cooler which is nice
